Steps to Predicting the Products of Chemical Reactions

WebMay 5, 2016 · They can predict with some certainty what type of reactions do what to which substances and then act on that prediction. When we learn chemistry, we are taught to recognize if a molecule belongs to a certain class with characteristic behavior. WebEach step usually involves reaction at only one chemical bond in the molecule. In planning the route of chemical synthesis, chemists usually visualize the end product and work backward toward increasingly simpler compounds. For many compounds, it is possible to establish alternative synthetic routes. t shirt originali bambino
